IIIACHINI,"V FOR MAKING BUTT-HINGES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ADRIAN RAIS, of Waterbury, in the county ot' New Haven, and State of Connecticut, have invented a new and useful improvement in Machinery for Making Butt-Hinges; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure 1, Sheet 1, is a plan'of my improved machine for making butt-hingcs.

This invention relates to improvements in machinery for the manufacture of butt-hinges, and consists in mechanism so constructedand arranged that the two match-blanks of a hinge are conveyed by automatic devices from two'feed-boxes or hoppers to the dies for bending the knuckles, thence to the milling-wheels or disks, and thence to a. central pointwhere the leaves of' the two match-blanks arc joined or intcrlocked, when another automatic device inserts the nail or rivet, and the butt-l1inge is finished and discharged.'

My improved machinery, therefore, 'executes the several parts or processes of manufacture in making butthinges by one connected and continuous operation, beginning with the two match-blanks, which are fcd into the machine at opposite sides, and ending withY the discharge of the butt-hinges complete.

Inv the construction of my improved machineryfor,working butt-hinges complete at one operation, by automatic devices which dispense entirely with hand work, I have employed some mechanical devices alrneady in use separately, a part of which devices relates to the bending of the knuckles of the blanks at one single operation, for which I have also applied for Letters Patent, and which are spcciiically disclaiined in the present application.

As a labor-saving machine, the advantage of this combination of devices for making butt-hinges without manipulation in the several parts or processes of manufacture will be readily appreciated; but I am enabled thereby also to accomplish what cannot be done by hand work. By thc old method of matching the right and left blanks by hand they have to be-selected for fitting into each other exactly, in order to insert tliehnail or rivet into the knuckles and to make the joints even and perfect. This work of matching the right and left blanks requires much labor, and many blanks have to he rejected as misiits, and are a loss, while the nail also requires riveting to secure them together.

By my improved machinery the right and left blanks are brought together and matched indiscriminately, so that' they shall all tit into each other, and the nail is introduced into the joint and. secured without riveting, while the knuckles and leaves are clamped do'wn evenly, and the butt-hingesY thus made are all made perfect without any loss of labor or waste of material. Y

A is the bed for the supportV of the machinery, and in iig. 11 are represented in plan view the various devices for performing the several dill'erent operations or processes required in thelmanufacture of a butt-hinge, begin ning with the vertical feed-boxes B B, placed on opposite sides of the bed-plate for receiving right and left blanks respectively, from which the blanks are drawn out by slides C C, which are actuated by cams E E on l l 66,626 l 2 l the driving-shaft The blanks are then pushed forward in front of the bending dies by arms a a, `on slides i C1 Cl, operated by side-levers D D, actuated by cams El El, also placed on .the shaft F, as are all'the earns in vthe machine.; and when the. blanks are deposited in front of the bending dies, which are not shown in the draw- 1 ings, they are pushed into them by slides C2 C2, actuated by cams E2 E2. The blanks are pressed and held in l place while the knuckles are bent by clamps G G, operated on by the long overhead leyers D.1 D1, connected with the rock-shaft F', all of which parts, and their operations severally and jointly, have been particularly described in my application for Letters Patent therefor previously referred to. Thus it will be seen that the l mechanism is arranged in pairs or duplicates, the parts on opposite sides ofthe bed A being'similar in eonstrucl tion and operation, and as this plan of the machinery is carried out in nearly all the devices for making the butt-hinges hereinafter to be described, the details of one of the duplicate parts only will be specially described in some cases, 'and the let-ters and figures of designation will be the same for the same parts on the opposite sides of the machine. When the blanks have had their knuckles formed' by the bending dies they are then a moved forward by the arm al on slide-bar C1 in front of the milling-disks H, which are constructed in the usual manner for milling or dressing the joints and bevclling the bottom of the spaces in the knuckles. The millingdisks are covered also by cap plates for protecting them fromdust, and under them are openings inthe bed plate to discharge the metal chips. The cap b has gates or openings, c c, figs. 5, (i, and T, on the front lower end corresponding with the number of the joints in the knuckles of the blanks in order te admit them. The l gates c c are n mde tapering in such manner that they shall act as guides and gauges to regulate the admission ofthe blanks for the purpose of milling them when they are pushed in to the disks by slide C3, actuated-forward l by cam E3, and drawn back by the spring M2. rllhe blanks are held in place while they are milled by the point l of a small lever-clamp, d, pivotcd on the fore end of slide C, that receives its clamping movement from an incline on a cross-bar, c, by which the rear end of the lever-clamp is raised, when the slide moves forward, as shown clearly in (sectional view, fig. il, sheet 2. Provision is made for withdrawing the blank from the milling-disk by any suitable mechanical device. 'After the blanks have been milled they are moved forward by the arm a? on the slide-bar C, to bc placed upon the ends of wings or pivoted arms I I, while the wings are open and are in a position in line with the movement of the slide-bar C1. I After receiving the blanks the wings -I I are closed Aby turning on their pivots g-g, in order to bring the right and left blanks of a hinge facing eachother under abox,

'.l, which covers clamping and guiding devices subsequently described. '.lhe wings I I are moved by mechanism under the bed of the machine, connected with slide C4, actuated by cam Eh The operating mechanism of the wings is exhibited in reversed plan view, iig. 2, and in sectional detail, tig. 10, sheet 2. The pivots g g of the wings I I pass through the bed-plate, and are affixed to the axes of two segmental teethed wheels, K K, iig. 2, geared together and connected by a rod, Z, with slide-bar C, which gives the wings their closing movement when it moves forward, while their retrograde, or the opening movement of thc wings, is accomplished bya spiral spring, M, in conjunction with ,the spring M', that acts directly on'slde C, so that together they draw back the slide-bar C4, in order to reverse the gear g g, by which the wings I I are directly actuated and opened. The match-blanks are carried from the opposite milling-disks Il by the wings I till they meet under the box J, with l their joints and spaces in the knuckles facing each other, and on the under side of the box J are guides L, for l directing the knuckles ofthe blanks into each other as they are brought together by the wings, as shown in gs.

4, 5, G. Behind the leaves of the blanks are shoulders q q, on the wings I I, which crowd the blanks into the ab; guides, and thus unite the right and left knuckle joints to make a pair of hinges.

The next operation in order is to introduce the wire nail or rivet. For this purpose suitable wire is cut into proper lengths -by a pair of shears, k, as it comes from rolls N, in the ordinary manner, from which shears the nailsfare pushed forward into position in front of and in line with the hole in the knuckle of the united blanks; or, instead of cutting the nails off, and feeding them in this manner directly from the shears they can be cut in a separate machine and conveyed from a hopper. The slide O5 pushes the nails in front of the match-blanks,' and is actuated by the sidelever D. The nail being in position, and lying in agroove inline with the hole in the knuckle-joint of the blanks is then pushed end foremost into the hole by means of a punch, m, fixed on the end of slide C, which is pushed by aiconnecting-rod, O, placed under the bed of the machine, and connected with slide C7, actuated by cam E". The rod O is also connected with a lever, n, for operating the slide C" and the punch m, to push in the nail, as shown clcarlyfin figs. 2, 10, sheet 2. The slide O7is drawn I back by a spiral spring, M, like the slides C3 C", by their springs Ml M2, and all the slides that are actuated by the cams on the shaft F are also provided with similar springs for the same purpose, as shown in figs. 9, 10,

11. After the nail has been pushed into the joint of the blanks, and has thus connected them, the knuckles are then levelled by the compression. of avertical clamp, P, which is operated by the lever D2, actuated by cam l Y? E6. The clamp P is provided with a spiral spring, p, to raise it, and the lower end t' is grooved to fit on the` knuckle-'joint of the blanks placed directly underneath, as seen in iig. 5.

New the operation of clamping the knuckle to set .and level the joints is a new process in the manufacture of butt-l1inges, and as the result is very important in regard to their finish, and economy in the manufacture, se, this point in my improvements is one requiring especial consideration. i

In the irst place, as hereinbefore stated, by the ordinary method of coupling the match-blanks in pairs for making a' butt-hinge, they are selected to fit each other, in order to insert the nails, and this is donc for the reason that thc knuckles are closed or bent around entirely in the operation of bending, and the joints do not all agree. By my improved method of manufacture the knuckles are not entirely bent around and closed, but are bent only so far around as to leave the hole' in the match-blanks when united large enough to receive the nail easily. And when the blanks are brought together as described under the bex J, and within the guides 7L, they are held firmly together by springs s s, placed on opposite sides of the box andthe guides, while the clamp P is pressed down upon the knuckle-joint of the match-blanks, as shown in fig. 5, sheet 1. By this means the knuckles of the matchblanks are entirely closed by the lateral pressure of th guides, andthe joints are levelled down upon the nail by the vertical pressure of the clamp, so as to make a n `ectly smooth-finished butt-hinge,

Vwhich its the nail and is superior to any hitherto manufactured. The ma ch-blnnks all come together, and

therefore none are wasted or 10st. As soon. us the clamping of the joints is done the wings I I retire to receive other blanks from the milling-disks, and the finished hinges full through an opening'in the bed of the machine into a box or other receptacle below. v

The 'general combined operation of the machinery will be suilciently understood bythe special description of the variousparts which has preceded, without further explanation.

' Having described my invention, und the mode of performing the same, I claim as new, and desire to secure by Letters Patentl y 1. The closing and opening Wings I, in combination vwith the milling-disks H, constructed and operating substantially as and for the purpose herein described.
